Application filed February 25, 1920. Serial No. 361,339.

To all whom t may concern:

Be it known that l, Corman lllnnznn, a citizen oi the United States, residing` at Los rngeles, in the county oi Los Angeles and state of Calitornia1 have invented new and useful lmprovenien lValls, of which the 'liollovi'fing` is a specification.

This invention relates to Walls andpartitions of monolithic and plastered components and the method ot makin@` the `finished Wall, and the invention has tor its object to provide tor the construction or, a substantial Wall or partition oi cellular structure having; one of its elements of monof lithic iorm and having applicable thereto a series ci plaster plates formingthe cellular features, and the invention consists ot the method and the product thereof, an embodiment ot' the invention being illustrated in the accon'ipanying drawings and described and claimed herein. 0

Figure l is a horizontal sectional vienT oi a portion of a Wall in the course ot construction showing` the molds applied thereto.

Fig. 2 is a plan view of a side Wall and an intermediate partition with connectingvgirders or lioists for forming a floor or other horizontal component.

Fig. 3 is a vertical sectional view `ol the structure shown in plan in Fig.` 2, certain parts being` in elevation.

Fig. i shows a horizontal sectional view through a partition component of the structure illustrating a further step in the method. a

'5 is a sectional vieiv on a vertical plane on line 5-5 of Fig. 3 showing` a partially completed licor. y y

The improved method consists in theutilization ot a suitable set ot vertical forms including side panels 2 and 3 oiiialse `Work, these panels being of any predetermined length and height in sections according to the dimensions oi the finished Wall or partition part, the side panels i2', preiterablyz being plane on the inner tace as at Z While the side mold panels 3 are provided with inwardly extending portions 3" the eatension being of any suitable Width and the ends ot the extensions beingsuitably spaced so as to torni vertical channels or chamber spaces as at 3a.

rlhe plastic cementitious material` to produce a monolithic structure is then poured into the chamber so as to produce a sub- `the channels or pockets 3a.

iu lllethods oi ll/ialring stantially continuous Wall structure W with a series of inwardly extending and vertical ribs or furringF strips d complementary to n Therefore by this step the solid Wall JV `is yproduced having the vertical and parallel rib members l `Which are spaced at any suitable distance horizontally. li any intermediate partition is to be formed in the structura mold members such as 37 are set in opposition `to each `other with the channel formingv projections or'extensions directly opposite so that when the cement is passed into the mold chamber thus termed a partition Wall of the structure plainly shown in Fig. 4l vat l is produced, the body yet the Wall having on opposite sides the salient vertical ribs or abutment members da.

ln practice the Wall parts `W and the partition` portions l?, it any are used, are all i completed to a suitable height as tor instance one story `at a time from the ioundation and then on the top plane of the `Walls and the partition there is placed a monolithic cement plate7 5 properly leveled up and the plate 5 is, preferably, ot a Width somewhat less than the total thickness of a Wall part W' at` the cross section through one of the vertical ribs #l as shown in The inner edge of the plate or plates 5 is,` plumbed up with the plane ot the faces ot the several ribs 4i thus leaving` a slight er.- posed top shoulder 6 above the body portion or the Wall "W and partition P.

@n this plate course there is then laid a set of joistor l`fgirder members J of such length as to extend transversely ironi parallel plate to plate, the ends of the joists resting, as shotvn in Fig. 3, even with the outer edge of the plate 5, the other end of a joist J rests above a partition l? the joist end extends to the center plano oi the partition so as to butt with a contiguous joist as J extending beyond 'from the partition. The butt-ing ends of contiguous joists are securely interloclteo. as by side plates T which are placed against the side faces and overlap the ends and are bolted or otherwise secured as at `3 to holdy the joists l and J.

lt will be seen that the plates will there tore cover the upper" ends oi the chambers or spaces existing between the vertical ribs 4rand there may be applied against the alined faces of the ribs 4 sheets or panels 9, preferably, of hardened plaster, these thereand in the event thatpy fore covering' the recesses between the ribs 4.-4. and forming lchambers l0, the tops ot which are covered by the plates 5. The plaster boards or panel members 9 may be secured in place against the ribs 4- by any suitable means as for instance by loops ot wire or other tying means 1l.

It is understood that such a method ot procedure will complete one complete story and the upper stories can be erected successively in similar manner by the proper arrangement of the molds 2 and 3 as the construction proceeds. y

lln order to secureV the interlock of the joists .l in the. side walls as they are cX- tended upwardly from the shoulder 6 the ends 'of the joists are provided with anchors A., for instance. shown at ihead parts ot these tees standing` in the plane ot' Vthe wall part W so that they will be embedded in the cementitious material as it is introduced in the mold chambers formed above the upper ends .of each story of the wall.l l

A ,iozor or'ceilingstructure is formed on and between the joists J. as shown in Fig. rlhe joists J are preferably of I-beam structure and are, preferably, of cementitious monolithic type, and between and on the lower parallel iianges ot' the joists J is laid in a common plane a set of ceiling' blocks B ot hardened plaster previously molded to a dimension corresponding` to the pitch oi" the joists J. n V- Each block B has a lower body portion ot a width substantially equal to the space between the bottom flanges otp'arallelrjoists J-J, and vthe upper or top portion of each bloclr is widened as by vflanges 7) designed to overlap and rest upon the Bauges at the bottoms of the joists J. After a's'etv oiu .the blocks has been arranged, as shown in Fig. 2. upon the respective vianges so as to complete the ceiling' portion throughout the length of the space between a pair ot `ioists.v

there is then introduced between each of the pairs of joists a Vset of arches C, each arch et suitable length and of width substantially equal to the distance between the webs ot the joists J the arches C resting upon the Hange portions 7) of the supporting blocks B.

said wall exposed, and then pourin The arches are ot such diniensionsas to present their crowns or top portions approximately in or below the top plane of the `ioists t-fl', as shown in Fig'. The armes C are, preferably, made ot plaster material as are also the blocks B.

rlfhe space that is formed between the top surface ot each ot the sets or arches C and the tops of the joists J then filled by any cementitious plastic material at tov form a substantial ii ling); or body that be leveled ott smooth with the tops oit the joists .l to form a iloor surface.

From this it will be seen that while a iioor or ceiling' component is built up of composite cement and plaster Members it is at the saine time hollow and substantial.

A finishing coat ot plaster or other inaterial may then be applied throughout the inner and outer surfaces that to be finished oit, such finishing coat being' indicated at'D in Fig. 5. The finishing' coat can be applied to the eX-terior surface ot the wall or partition as well as to the interior surta ce and may form a ceilingl or may forni a door surface as desired.

Various changes may be made without departing' from the spirit oil the invention as claimed.

`What is claimed is:

The herein described method ot producing' monolithic walls. which consists in pouring` concrete so as to torni wall having: on one face a series ot vertically disposed ribs that are spaced apart to form relatirely wide shallow channels` then covering` the upper ends ot said ribs and closing; the upper ends ot' said channels and leaving the 1great-er portion of the top surface ot the body ot concrete on top of the upper portion oit said wall to form an upper wall sect-ion having` on one ot its faces a series ot vertically disposed ribs that coincide with the ribs on the lower wall section and the 1lower portion of said upper' wall section bearing' directly upon and being` bonded to the upper surface ot the lower wall section.

In testimony whereof I have signed my name to this specification.
